 ## Drivers
 
-The `persist` framework defines an API for storing key/value pairs. You also need a driver for the framework. When configuring your application if you want to use `persist` you have to add it to the application and indicate what driver you are going to use. `Hummingbird` comes with a memory based driver ``Hummingbird/MemoryPersistDriver`` which will store these values in the memory of your server.

 ```swift
 let persist = MemoryPersistDriver()
 ```
 If you use the memory based driver the key/value pairs you store will be lost if your server goes down, also you will not be able to share values between server processes. 
 
 ### Redis
 
-You can use Redis to store the `persists` key/value pairs with ``HummingbirdRedis/RedisPersistDriver`` from the `HummingbirdRedis` library. You would setup `persist` to use Redis as follows. To use the Redis driver you need to have setup Redis with Hummingbird as well.
